Technical Field

[0002] Electric suspension crane, also known as electric single-beam crane, is an important material handling equipment with the advantages of compact structure, light weight, small wheel pressure, etc., so it is widely used in warehouses, factories, workshops and other occasions, especially suitable for short-distance, frequent use, intensive lifting operation environment, which can greatly improve production efficiency and reduce the labor intensity of workers. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN221027292U discloses a double-hanging-point electric suspension beam crane, wherein the left and right outer walls of the cross beam are both provided with driving plates, the front and rear outer walls of the cross beam are both provided with guide rails, the lifting mechanism includes a winder, and a hanging plate is fixedly installed on the top outer wall of the winder. The lifting position of the double-hanging-point electric suspension beam crane is often limited by the position of the cross beam and the supporting structure, resulting in the need to increase the lifting range as much as possible during the installation of the crane to improve the convenience of use, but this will lead to an increase in the cost of the crane;

However, when the height of the beam is high or the environment is dim, it is often difficult for workers to quickly determine the position of the hook, and thus they cannot quickly make corresponding preparations, reducing the transportation efficiency of heavy objects. Constantly looking up to determine the position of the hook will greatly increase the labor intensity of the workers. Utility Model Content

When adjusting the lifting position, after the crossbeam and the positioning component are moved to a suitable position, the rotating motor is controlled to drive the lifting structure body to rotate, which can further drive the support plate to rotate and adjust the position of the hook, thereby greatly improving the lifting range of the crane. At the same time, there is no need to increase the length of the crossbeam and the supporting structure, thereby reducing the cost of the crane.
